An investigation of the radiations from the mass-120 isobars has heen made using magnetic lens, scintillation pulse-height, and coincidence counting techniques. Sb/sup 120m/ decays with a 5.8-day half life by electron capture, positron emission if any <0.03%, to an 11- mu sec level of Sn/sup 120/ which then decays by the emission of the following gamma rays (energies in Mev):0.089 (E1), 0.199 (E2), 1.04 (E2), and 1.18 (E2). The 1.1B-Mev gamma ray also occurs in the decay of the 16-min Sb/sup 120/ , where the number of gamma rays per positron is 0.03. An activity of ~ 55 sec is assigned to In/sup 120m/. A decay scheme is proposed. (auth)
